Pressure damper for recoilless weapons

Abstract

Pressure damper for recoilless weapon designed to reduce the pressure in the area around and immediately to the rear of the muzzle of the barrel. A container with liquid is placed in the barrel close to its muzzle or in a forward extended portion of the barrel and arranged to be burst when the weapon is fired so that the liquid is suddenly released and mixed with the gases from the powder.

We claim: 
     
       1. The combination of a pressure damper and a recoilless weapon having a barrel and a muzzle, the pressure damper designed to reduce the pressure in the area around and immediately to the rear of the muzzle of the barrel and comprising at least one container filled with a liquid which is so located in the muzzle region of the barrel that, when the recoilless weapon is fired, the at least one container bursts and as a result explosively releases the said liquid, so that said liquid is mixed with powder gases to reduce the pressure of the powder gases, said at least one container is cylindrically shaped and defines a plurality of apertures aligned parallel to a longitudinal axis of the barrel when said at least one container is located in the barrel, said plurality of apertures permitting gases to leak from the muzzle ahead of a projectile being fired from said barrel before said projectile reaches said at least one container to prevent bursting of the container by other than contacting said projectile. 
     
     
       2. The combination of a pressure damper and a recoilless weapon having a barrel and a muzzle, the pressure damper designed to reduce the pressure in the area around and immediately to the rear of the muzzle of the barrel and comprising at least one container filled with a liquid which is so located in the muzzle region of the barrel that, when the recoilless weapon is fired, the at least one container bursts and as a result explosively releases the said liquid, so that said liquid is mixed with powder gases to reduce the pressure of the powder gases, said barrel is of uniform diameter except for a forward extension section of the barrel which defines an enlargement that terminates at the muzzle, the muzzle having a diameter greater than the diameter of the barrel, the portion of the barrel extending from the uniform diameter portion being of conical shape tapered outwardly, the portion of the barrel extending from the muzzle being of conical shape and tapered outwardly, the two conical shaped portions being interconnected by a portion of cylindrical shape, said at least one container being in the form of a flattened toroid having a complementary shape to the cylindrical portion of the enlargement to fit snugly therein and having an opening diameter greater than the uniform diameter of the barrel.
